Only let authorized persons do maintenance, examine, or replace components on the drive.
Read this manual carefully and know all the precautions and safety information before installing, wiring, repairing, or
examining the drive or replacing components.
Examine and maintain the drive and peripheral devices regularly to extend the life of the drive and decrease
performance deterioration, decrease early wear, and decrease drive failures.
Regular examinations and maintenance will also decrease system downtime.
Refer to the Technical Reference (SIEPC71061732) for more information about maintenance and examinations.
Examine the drive one time each year at a minimum.
The operating conditions, environmental conditions, and use conditions will have an effect on the examination
frequency for connected equipment.
